'Rim' in the Bible

Gourds [were] under its rim surrounding it all around; ten to the cubit, surrounding the sea all around with two rows of gourds, [which] were cast when he cast the metal.

Its thickness [was] a handbreadth, but its rim [was] as the work on the brim of a cup, [like the] bud of a lily; it held two thousand baths.
